Serial No. 112,814.

This invention relates to fabricated roofing of a type whichis commonlymade of a base of felted fibrous sheet material saturated with awaterproofing asphaltic compound and coated with layers of imperviousmaterial,

such as blown or high melting-point asphalt and granular material.

In the manufacture of roofing elements of this type, material for thebase is usually made from a pulp ofrag, asbestos or other suitablefibers, and formed into sheets on-a papermaking machine. This feltedfibrous sheet material is preferably saturated with an asphalticcompound, the saturant either being mixed with the pulp in the form ofan emulsion, or applied in liquid form to the dried sheet. one or bothsides with a suitable coating compound, such as blown asphalt which, byreason of its tough rubbery consistency at ordinary atmospherictemperatures and its relatively high melting point, is generally usedfor this purpose. To protect the asphalt from the deteriorating actionof the weather,

it may be surfaced with suitable granular or comminuted material, suchas crushed slate, tile, brick, or the like. Pulverulent material, suchas .powdered mica or chalk dust,- may be substituted for the granularmaterial on areas which are not exposed to theflweather when the elementis laid, to prevent adjacent 7 elements from sticking together whenpackaged for shipment. The roofing elements are then cut or otherwiseseparated from the sheet, being given any, desired size or shape. Suchelements ,may be individual shingles or may be strip shingles, socalled, .with a plurality of tabs simulating individual shingles. Thismethod of making roofing elements is capable of considerable variationboth in so quence of the various steps and in the mannerof carrying outeach step. By whatever process the elements are made, there is bound tobe a certain percentage of seconds or elements with imperfections ofonekind or another which prevent'their being sold in the form and gradeintended. The imperfections in such elements are often slight, and of anature which in no way detracts from the protective qualities of theelement. By my The saturated sheet is then coated on invention, I amable to reclaim and utilize a large proportion of seconds and thusprevent a-large waste of costly material. This may be done by cutting ortearing material from the butt edges or portions of the elements so asto remove the imperfect parts and at the same time produce an elementwhich will have irregularities of shape which offer great possibilities:for artistic efi'ects, avoiding the monotonous regularity whichcharacterizes elements of uniform shape when laid on a roof. Y

After cutting or tearing the elements to irregular shapes, I may applyan additional coating of blown asphalt or the like to the whole surfaceor the exposed portion thereof, this coat also covering and sealing thecut edges. A surfacing of granular material may-then be applied to thecoat, this granular material being of a number of colors if desired.Where a plurality of colors are used,

it is preferred that each color occupy a definite area substantiallycoextensive with that portion of a shingle strip which corresponds to anindividual shingle. The additional layer of asphalt and grit also coverssurface imperfections and adds materially to the thickness of theelement, thus giving it a more substantial appearance.

My invention is not to be limited to the reclamation of factory seconds,as I may start, with the coated and slated sheet material, cut orotherwise separate elements therefrom with irregularly shaped tabs, thenapply an additional-coating, sealing the cut edges, and surface thecoating with grit which may be of a variety of colors arranged ashereinbefore described.

Further advantageous features will be apparent from the disclosure inthe description which follows, and from the drawings, of

' which,

Figures 1 and 2 illustrate strip shingles I having tabs of differentgeometric shapes and different colors.

Figure 3 indicates the effect produced by a number of such stripshingles laid in overlapping courses. I

, Figures 4 and 5 show in cross section two examples of the structureswhich may be ferent shapes. The extensive cut-away por-- tions make thistype of strip shingle particularly valuable in the reclamation offactory seconds which may have slight imperfec tions such as cuts ortears in one or more of the tabs. The forms illustrated in these figuresare illustrative of a large variety of combinations of shapes which canbe made. In addition to various shapes for the several tabs, it ispreferred to have a variety of colors, each color being confined to aportion of the strip shingle which corresponds to one tab. Thus inFigure 1, for example, a three-tab strip shingle is shown, one of thetabs 10 being pointed, another tab 11 having a semi-hexagonal shape,while the third tab 12 is semi-circular. These different tabs aresurfaced with solid colors, the color of each tab being different fromthat of the adjacent tab. In reclaiming defective strip shingles, thedefective portions may be cut out in any convenient manner so as to formtabs of desired shape, the shape being governed somewhat by the natureand extent of the defects. After the strip shingle has been cut toshape, it may be coated with suitable impervious material, such forexample as blown asphalt or the like, this coating being applied overall the surfaces and edges of the element, or merely to the exposedsurface and edges, or to any extent between these. While the coating isstill hot and sticky, granular material of any desired kind, such ascrushed slate, brick, tile, or other equivalent, may be applied, grit ofdifferent colors being used for the several tabs of the element. Figure4 shows in cross section a refinished element comprising a fibrous core13 of felted sheet material, preferably saturated with liquefied oremulsified asphalt. On either side of this felt sheet is a coating 14 ofblown asphalt or the like, surfaced'with grit 15 on both sides of theelement. The refinishing coat 16 of blown asphalt covers the grit layers15 and extends in a continuous film around the butt end of the elementas at 17. This outer coating of asphalt is overlaid with a second layer18 of grit which may be applied to the upper and lower surfaces of theelement as shown, orsimply to the upper surface and the edge. Figure 5is a section similar to Figure 4 showing a refinished element whichoriginally was coated on both sides with layers 16 of blown asphalt, butwas finished with grit 15 on one side only. As previously described, asecond coating of blown asphalt may be applied over the exposed surfaceand edges, or over the entire surface of the element, the r-ecoatedportions being re-surfaced with an additional layer 18, different colorsof grit being preferably used for the several tabs. It will be apparentthat many variations are possible in the extent of the portions coatedand surfaced with grit in the refinishing process, the examples given inFigures 4 and 5 being by way of illustration only.

Figures 6 and 7 illustrate two varieties of strip shingles which aremade up to give an appearance of irregularity and roughness to the roofas a whole. The tabs on the element shown in Figure 6, for example, maybe shaped by cutting or tearing so as to resemble the projecting ends ofrough slabs of stone or tile. In the form illustrated in Figure 7, theusual straight line edges of the tabs are relieved by wavy or jaggedlines, the regularity of effect being further eliminated by thedifference in width of the tabs. In these forms also it is preferable toapply the final surfacing layer of grit so that each tab will have asolid color different from other tabs in the strip, although if desiredtwo or more adjacent tabs may now and then be given the same color. Whenstrip shingles are made up with tabs,of unequal width as in Figures 6and 7, it is preferred to regulate the widths of the tabs so that theywill be limited to either thirds or fifths of the standard width. Whenlaying such elements on a roof, the elements in successive coursesshould be offset laterally a distance equal to half the standard widthof a tab. This will avoid the possibility of a slot between tabs of oneelement coinciding with the line of abutment between adjacent elementsin the course below, a situation which would reduce the protectionafforded by the roofing elements and would be liable to cause a leak atthat point. By regulating the widths ofthe tabs as stated; such acontingency is avoided and all abutting lines of adjacent elements arecovered by some portion of a tab, thus insuring complete protection.

It is to be understood that the invention is not to be limited by theembodiments shown and described herein, but is subject to such changesand modifications as fall within the scope of the appended claims.

I claim:

1. The process of refinishing strip shingles having shingle-simulatingtabs, which comprises tearing away portions of said tabs to alter theoriginal shapes thereof and to produce irregularly shaped edges, coatingthe exposed surfaces of the element with an impervious compound, andsurfacing the coated areas with comminuted material.

2. The process of refinishing imperfect strip shingles hayingshingle-simulating tabs, which comprises re-shaping said tabs into avariety of shapes by the removal of portions thereof, coating theexposed surfaces and edges of the element with an impervious compound,and applyin granular miterial of difl'erent colors to t e several 'ta s.i

3. The process of refinishing shingles, which comprises tearing awayportions of the butts to alter the original shapes thereof and toproduce irregularly shaped butt edges coating the exposed surfaces andedges of the shingle with an impervious compound, and surfacing thecoated areas with comminuted material.

In testimony whereof I have aflixed my signature. FREDERICK C. OVERBURY.
